Embodiment 1

[0018] Take 400 g of dried Codonopsis root powder, add 4000 mL of water, soak for 2 h at room temperature, and extract with an ultrasonic circulation extractor with an ultrasonic frequency of 45 kHz and a power of 750 W. The total extraction time is 40 min, and the ultrasonic time and interval are 2 s / 1 s, stirring speed 1300 r / min. After the extraction was completed, filter, and the filter residue was extracted twice with the same amount of water under the same conditions, and the three extracts were combined, centrifuged at 4000 r / min for 20 min, and the supernatant was filtered through a microfiltration membrane with a membrane pore size of 200 nm. Then filter with an ultrafiltration membrane with a membrane pore size of 10 kD, and distill and concentrate the permeate under reduced pressure to obtain the natural tobacco flavoring agent Ⅰ.

[0019] Dilute the flavoring agent Ⅰ with a mixed solvent of an appropriate amount of water and propylene glycol (9:1, mass ratio), add ...

Embodiment 2

[0023] Take 50 g of dried Codonopsis root slices, add 500 mL of 95% ethanol, soak at room temperature for 2 h, heat to reflux for 0.5 h, filter, and use the same amount of 95% ethanol to extract twice under the same conditions, and combine the three extractions centrifuged at 4000 r / min for 20 min, the supernatant was filtered through a microfiltration membrane with a membrane pore size of 50 nm and then filtered with an ultrafiltration membrane with a membrane pore size of 5 kD, and the permeate was concentrated by distillation under normal pressure to obtain Natural tobacco flavoring agent Ⅱ.

[0024]Take 3 g of natural tobacco flavoring agent II, dilute with 10 g of 80% ethanol, spray the diluent evenly on 1 kg of expanded cut stems, seal the cut stems, place them at room temperature for 6 h, press 5% ( mass fraction) was evenly mixed into flue-cured tobacco-type cigarette formula shredded tobacco, and the control was the same kind of flue-cured tobacco-type cigarette formu...

Embodiment 3

[0028] Take 400 g of dried Codonopsis root powder, add 4000 mL of a mixed solution of water, ethanol and 1,2-propanediol, the mass fractions of water, ethanol and 1,2-propanediol are 50%, 45% and 5%, respectively, at room temperature Soak under water for 2 h, ultrasonic-assisted extraction for 1 h, ultrasonic frequency 45 kHz, power 750 W, ultrasonic time and interval time 2 s / 1 s, stirring speed 1400 r / min. Filtration, the filter residue was extracted twice under the same conditions with the mixed solution of water, ethanol and 1,2-propanediol in the same amount and combination ratio, and the three extracts were combined, centrifuged at 4000 r / min for 20 min, and the supernatant was passed through After filtering with a microfiltration membrane with a membrane pore size of 100 nm, it was filtered with an ultrafiltration membrane with a membrane pore size of 8 kD, and the permeate was concentrated by distillation under reduced pressure to obtain the natural tobacco flavoring ag...

Abstract

The invention discloses application of a codonopsis pilosula extract in cut stems or reconstituted tobaccos. The application is characterized in that the codonopsis pilosula extract is added into the cut tobacco stems or the reconstituted tobaccos, so that wood gas (miscellaneous gas) and the irritation in the cut stems or the reconstituted tobaccos can be obviously reduced, the blending rate of the cut stems or the reconstituted tobaccos in the formula of medium- and high-grade cigarettes is increased, the smoke tar in the cigarettes is reduced, the cigarette production cost is reduced, and the smoke quality of the cigarette cannot be affected; the codonopsis pilosula extract is prepared by performing solvent soaking, extraction, refining and concentration on codonopsis pilosula serving as a raw material. The application disclosed by the invention has the outstanding characteristics that new application of the codonopsis pilosula is developed by a conventional solvent and a common extraction method, so that a novel natural flavoring agent for the cigarettes is prepared.

Description

technical field [0001] The present invention relates to the field of tobacco additives, in particular to the application of Codonopsis pilosula extract in shredded stems or reconstituted tobacco leaves. The extract is applied to shredded tobacco stems or reconstituted tobacco leaves, which can significantly reduce the woody gas and Stimulation, increase the blending ratio of cut stems or reconstituted tobacco leaves in cigarette formula, without affecting the smoke quality of cigarettes. Background technique [0002] Tobacco stems, the main veins of tobacco leaves, account for about 25% to 30% of the weight of tobacco leaves. my country is a big tobacco producing country, producing about hundreds of thousands of tons of tobacco stems every year. The main component of tobacco stems is cell wall substances, accounting for more than 40%, including cellulose, hemicellulose, pectin and lignin. When the tobacco stems are burned, the pyrolysis of these substances will produce mor...
